+GIT v1.6.0.3 Release Notes
+==========================
+
+Fixes since v1.6.0.2
+--------------------
+
+* "git archive --format=zip" did not honor core.autocrlf while
+ --format=tar did.
+
+* Continuing "git rebase -i" was very confused when the user left modified
+ files in the working tree while resolving conflicts.
+
+* Continuing "git rebase -i" was also very confused when the user left
+ some staged changes in the index after "edit".
+
+* "git rebase -i" now honors the pre-rebase hook, just like the
+ other rebase implementations "git rebase" and "git rebase -m".
+
+* "git rebase -i" incorrectly aborted when there is no commit to replay.
+
+* Behaviour of "git diff --quiet" was inconsistent with "diff --exit-code"
+ with the output redirected to /dev/null.
+
+* "git diff --no-index" on binary files no longer outputs a bogus
+ "diff --git" header line.
+
+* "git diff" hunk header patterns with multiple elements separated by LF
+ were not used correctly.
+
+* "git gc" when ejecting otherwise unreachable objects from packfiles into
+ loose form leaked memory.
+
+* Hunk headers in "git diff" default to using extended regular
+ expressions, fixing some of the internal patterns on non-GNU
+ platforms.
+
+* New config "diff.*.xfuncname" exposes extended regular expressions
+ for user specified hunk header patterns.
+
+* "git index-pack" was recently broken and mishandled objects added by
+ thin-pack completion processing under memory pressure.
+
+* "git stash apply sash@{1}" was fixed to error out. Prior versions
+ would have applied stash@{0} incorrectly.
+
+* "git stash apply" now offers a better suggestion on how to continue
+ if the working tree is currently dirty.
+
+* "git for-each-ref --format=%(subject)" fixed for commits with no
+ no newline in the message body.
+
+* "git remote" fixed to protect printf from user input.
+
+* "git remote show -v" now displays all URLs of a remote.
+
+* "git checkout -b branch" was confused when branch already existed.
+
+* "git checkout -q" once again suppresses the locally modified file list.
+
+* "git clone -q", "git fetch -q" asks remote side to not send
+ progress messages, actually making their output quiet.
+
+* Cross-directory renames are no longer used when creating packs. This
+ allows more graceful behavior on filesystems like sshfs.
+
+* Stale temporary files under $GIT_DIR/objects/pack are now cleaned up
+ automatically by "git prune".
+
+* "git merge" once again removes directories after the last file has
+ been removed from it during the merge.
+
+* "git merge" did not allocate enough memory for the structure itself when
+ enumerating the parents of the resulting commit.
+
+* "git blame -C -C" no longer segfaults while trying to pass blame if
+ it encounters a submodule reference.
+
+* "git rm" incorrectly claimed that you have local modifications when a
+ path was merely stat-dirty.
+
+* "git svn" fixed to display an error message when 'set-tree' failed,
+ instead of a Perl compile error.
+
+* "git submodule" fixed to handle checking out a different commit
+ than HEAD after initializing the submodule.
+
+* The "git commit" error message when there are still unmerged
+ files present was clarified to match "git write-tree".
+
+* "git init" was confused when core.bare or core.sharedRepository are set
+ in system or user global configuration file by mistake. When --bare or
+ --shared is given from the command line, these now override such
+ settings made outside the repositories.
+
+* Some segfaults due to uncaught NULL pointers were fixed in multiple
+ tools such as apply, reset, update-index.
+
+* Solaris builds now default to OLD_ICONV=1 to avoid compile warnings;
+ Solaris 8 does not define NEEDS_LIBICONV by default.
+
+* "Git.pm" tests relied on unnecessarily more recent version of Perl.
+
+* "gitweb" triggered undef warning on commits without log messages.
+
+* "gitweb" triggered undef warnings on missing trees.
+
+* "gitweb" now removes PATH_INFO from its URLs so users don't have
+ to manually set the URL in the gitweb configuration.
+
+* Bash completion removed support for legacy "git-fetch", "git-push"
+ and "git-pull" as these are no longer installed. Dashless form
+ ("git fetch") is still however supported.
+
+Many other documentation updates.

See linkgit:git-update-index[1]. True by default.
+core.ignoreCygwinFSTricks::
+ This option is only used by Cygwin implementation of Git. If false,
+ the Cygwin stat() and lstat() functions are used. This may be useful
+ if your repository consists of a few separate directories joined in
+ one hierarchy using Cygwin mount. If true, Git uses native Win32 API
+ whenever it is possible and falls back to Cygwin functions only to
+ handle symbol links. The native mode is more than twice faster than
+ normal Cygwin l/stat() functions. True by default, unless core.filemode
+ is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's
+ POSIX emulation is required to support core.filemode.
+
core.trustctime::
If false, the ctime differences between the index and the
working copy are ignored; useful when the inode change time
variable. Note that git sets the `LESS` environment
variable to `FRSX` if it is unset when it runs the
pager. One can change these settings by setting the
- `LESS` variable to some other value or by giving the
- `core.pager` option a value such as "`less -+FRSX`".
+ `LESS` variable to some other value. Alternately,
+ these settings can be overridden on a project or
+ global basis by setting the `core.pager` option.
+ Setting `core.pager` has no affect on the `LESS`
+ environment variable behaviour above, so if you want
+ to override git's default settings this way, you need
+ to be explicit. For example, to disable the S option
+ in a backward compatible manner, set `core.pager`
+ to "`less -+$LESS -FRX`". This will be passed to the
+ shell by git, which will translate the final command to
+ "`LESS=FRSX less -+FRSX -FRX`".
core.whitespace::
A comma separated list of common whitespace problems to
you want to use an external diff program only on a subset of
your files, you might want to use linkgit:gitattributes[5] instead.
+diff.mnemonicprefix::
+ If set, 'git-diff' uses a prefix pair that is different from the
+ standard "a/" and "b/" depending on what is being compared. When
+ this configuration is in effect, reverse diff output also swaps
+ the order of the prefixes:
+'git-diff';;
+ compares the (i)ndex and the (w)ork tree;
+'git-diff HEAD';;
+ compares a (c)ommit and the (w)ork tree;
+'git diff --cached';;
+ compares a (c)ommit and the (i)ndex;

+'git diff --no-index a b';;
+ compares two non-git things (1) and (2).
+
diff.renameLimit::
The number of files to consider when performing the copy/rename
detection; equivalent to the 'git-diff' option '-l'.
`transfer.unpackLimit` is used instead.
format.numbered::
- A boolean which can enable sequence numbers in patch subjects.
- Setting this option to "auto" will enable it only if there is
- more than one patch. See --numbered option in

+ A boolean which can enable or disable sequence numbers in patch

'git check-attr' attr... [--] pathname...
+'git check-attr' --stdin [-z] attr... < <list-of-paths>
DESCRIPTION
-----------
OPTIONS
-------
+--stdin::
+ Read file names from stdin instead of from the command-line.
+
+-z::
+ Only meaningful with `--stdin`; paths are separated with
+ NUL character instead of LF.
+
\--::
Interpret all preceding arguments as attributes, and all following
arguments as path names. If not supplied, only the first argument will
be treated as an attribute.
+OUTPUT
+------
+
+The output is of the form:
+<path> COLON SP <attribute> COLON SP <info> LF
+
+Where <path> is the path of a file being queried, <attribute> is an attribute
+being queried and <info> can be either:
+
+'unspecified';; when the attribute is not defined for the path.
+'unset';; when the attribute is defined to false.
+'set';; when the attribute is defined to true.
+<value>;; when a value has been assigned to the attribute.
+
+EXAMPLES
+--------
+
+In the examples, the following '.gitattributes' file is used:
+---------------
+*.java diff=java -crlf myAttr
+NoMyAttr.java !myAttr
+README caveat=unspecified
+---------------
+
+* Listing a single attribute:
+---------------
+$ git check-attr diff org/example/MyClass.java
+org/example/MyClass.java: diff: java
+---------------
+
+* Listing multiple attributes for a file:
+---------------
+$ git check-attr crlf diff myAttr -- org/example/MyClass.java
+org/example/MyClass.java: crlf: unset
+org/example/MyClass.java: diff: java
+org/example/MyClass.java: myAttr: set
+---------------
+
+* Listing attribute for multiple files:
+---------------
+$ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java
+org/example/MyClass.java: myAttr: set
+org/example/NoMyAttr.java: myAttr: unspecified

+'git checkout' [
-f|--ours|--theirs|-m|--conflict=<style>] [<tree-ish>] [--] <paths>...
DESCRIPTION
-----------
When <paths> are given, this command does *not* switch
branches. It updates the named paths in the working tree from
-the index file (i.e. it runs `git checkout-index -f -u`), or
-from a named commit. In
-this case, the `-f` and `-b` options are meaningless and giving
+the index file, or from a named commit. In
+this case, the `-b` options is meaningless and giving
either of them results in an error. <tree-ish> argument can be
used to specify a specific tree-ish (i.e. commit, tag or tree)
to update the index for the given paths before updating the
working tree.
+The index may contain unmerged entries after a failed merge. By
+default, if you try to check out such an entry from the index, the
+checkout operation will fail and nothing will be checked out.
+Using -f will ignore these unmerged entries. The contents from a
+specific side of the merge can be checked out of the index by
+using --ours or --theirs. With -m, changes made to the working tree
+file can be discarded to recreate the original conflicted merge result.
OPTIONS
-------
Quiet, suppress feedback messages.
-f::
- Proceed even if the index or the working tree differs
- from HEAD. This is used to throw away local changes.
+ When switching branches, proceed even if the index or the
+ working tree differs from HEAD. This is used to throw away
+ local changes.
++
+When checking out paths from the index, do not fail upon unmerged
+entries; instead, unmerged entries are ignored.
+
+--ours::
+--theirs::
+ When checking out paths from the index, check out stage #2
+ ('ours') or #3 ('theirs') for unmerged paths.
-b::
Create a new branch named <new_branch> and start it at
off of "origin/hack" (or "remotes/origin/hack", or even
"refs/remotes/origin/hack"). If the given name has no slash, or the above
guessing results in an empty name, the guessing is aborted. You can
-exlicitly give a name with '-b' in such a case.

+ When switching branches,
+ if you have local modifications to one or more files that
are different between the current branch and the branch to
which you are switching, the command refuses to switch
branches in order to preserve your modifications in context.
paths are left unmerged, and you need to resolve the conflicts
and mark the resolved paths with `git add` (or `git rm` if the merge
should result in deletion of the path).
++
+When checking out paths from the index, this option lets you recreate
+the conflicted merge in the specified paths.
+
+--conflict=<style>::
+ The same as --merge option above, but changes the way the
+ conflicting hunks are presented, overriding the
+ merge.conflictstyle configuration variable. Possible values are
+ "merge" (default) and "diff3" (in addition to what is shown by
+ "merge" style, shows the original contents).
<new_branch>::
Name for the new branch.
Operate quietly. This flag is also passed to the `rsync'
command when given.
+--verbose::
+-v::
+ Display the progressbar, even in case the standard output is not
+ a terminal.
+
--no-checkout::
-n::
No checkout of HEAD is performed after the clone is complete.
-s::
--signoff::
- Add Signed-off-by line at the end of the commit message.
+ Add Signed-off-by line by the commiter at the end of the commit
+ log message.

--no-verify::
additional commits on top of the tagged object and the
abbreviated object name of the most recent commit.
+By default (without --all or --tags) `git describe` only shows
+annotated tags. For more information about creating annotated tags
+see the -a and -s options to linkgit:git-tag[1].
OPTIONS
-------
--all::
Instead of using only the annotated tags, use any ref
- found in `.git/refs/`.
+ found in `.git/refs/`. This option enables matching
+ any known branch, remote branch, or lightweight tag.
--tags::
Instead of using only the annotated tags, use any tag
- found in `.git/refs/tags`.
+ found in `.git/refs/tags`. This option enables matching
+ a lightweight (non-annotated) tag.
--contains::
Instead of finding the tag that predates the commit, find
refname::
The name of the ref (the part after $GIT_DIR/).
+ For a non-ambiguous short name of the ref append `:short`.
objecttype::
The type of the object (`blob`, `tree`, `commit`, `tag`).
If -o is specified, output files are created in <dir>. Otherwise
they are created in the current working directory.
-If -n is specified, instead of "[PATCH] Subject", the first line
-is formatted as "[PATCH n/m] Subject".
+By default, the subject of a single patch is "[PATCH] First Line" and
+the subject when multiple patches are output is "[PATCH n/m] First
+Line". To force 1/1 to be added for a single patch, use -n. To omit
+patch numbers from the subject, use -N
If given --thread, 'git-format-patch' will generate In-Reply-To and
References headers to make the second and subsequent patch mails appear

same and the index entries for them stay as they were,
i.e. matching `HEAD`.
+HOW CONFLICTS ARE PRESENTED
+---------------------------
+
+During a merge, the working tree files are updated to reflect the result
+of the merge. Among the changes made to the common ancestor's version,
+non-overlapping ones (that is, you changed an area of the file while the
+other side left that area intact, or vice versa) are incorporated in the
+final result verbatim. When both sides made changes to the same area,
+however, git cannot randomly pick one side over the other, and asks you to
+resolve it by leaving what both sides did to that area.
+
+By default, git uses the same style as that is used by "merge" program
+from the RCS suite to present such a conflicted hunk, like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+The area a pair of conflicting changes happened is marked with markers
+"`<<<<<<<`", "`=======`", and "`>>>>>>>`". The part before the "`=======`"
+is typically your side, and the part after it is typically their side.
+
+The default format does not show what the original said in the conflicted
+area. You cannot tell how many lines are deleted and replaced with the
+Barbie's remark by your side. The only thing you can tell is that your
+side wants to say it is hard and you'd prefer to go shopping, while the
+other side wants to claim it is easy.
+
+An alternative style can be used by setting the "merge.conflictstyle"
+configuration variable to "diff3". In "diff3" style, the above conflict
+may look like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+|||||||
+Conflict resolution is hard.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+In addition to the "`<<<<<<<`", "`=======`", and "`>>>>>>>`" markers, it uses
+another "`|||||||`" marker that is followed by the original text. You can
+tell that the original just stated a fact, and your side simply gave in to
+that statement and gave up, while the other side tried to have a more
+positive attitude. You can sometimes come up with a better resolution by
+viewing the original.
+
+
+HOW TO RESOLVE CONFLICTS
+------------------------
+
After seeing a conflict, you can do two things:
* Decide not to merge. The only clean-up you need are to reset

DESCRIPTION
This flag disables the check. This can cause the
remote repository to lose commits; use it with care.
---repo=<repo>::
- When no repository is specified the command defaults to
- "origin"; this overrides it.
+--repo=<repository>::
+ This option is only relevant if no <repository> argument is
+ passed in the invocation. In this case, 'git-push' derives the
+ remote name from the current branch: If it tracks a remote
+ branch, then that remote repository is pushed to. Otherwise,
+ the name "origin" is used. For this latter case, this option
+ can be used to override the name "origin". In other words,
+ the difference between these two commands
++
+--------------------------
+git push public #1
+git push --repo=public #2
+--------------------------
++
+is that #1 always pushes to "public" whereas #2 pushes to "public"
+only if the current branch does not track a remote branch. This is
+useful if you write an alias or script around 'git-push'.

------------------
merge, but it would not show in `git diff-index --cached $M`
output after two-tree merge.
+Case #3 is slightly tricky and needs explanation. The result from this
+rule logically should be to remove the path if the user staged the removal
+of the path and then switching to a new branch. That however will prevent
+the initial checkout from happening, so the rule is modified to use M (new
+tree) only when the contents of the index is empty. Otherwise the removal
+of the path is kept as long as $H and $M are the same.

specified on the command line, the user will be prompted with a ReadLine
enabled interface to provide the necessary information.
+
OPTIONS
-------
-The options available are:
+
+Composing
+~~~~~~~~~
--bcc::
- Specify a "Bcc:" value for each email.
+ Specify a "Bcc:" value for each email. Default is the value of
+ 'sendemail.bcc'.
+
The --bcc option must be repeated for each user you want on the bcc list.
+
The --cc option must be repeated for each user you want on the cc list.
---cc-cmd::
- Specify a command to execute once per patch file which
- should generate patch file specific "Cc:" entries.
- Output of this command must be single email address per line.
- Default is the value of 'sendemail.cccmd' configuration value.
-
---chain-reply-to::
---no-chain-reply-to::
- If this is set, each email will be sent as a reply to the previous
- email sent. If disabled with "--no-chain-reply-to", all emails after
- the first will be sent as replies to the first email sent. When using
- this, it is recommended that the first file given be an overview of the
- entire patch series.
- Default is the value of the 'sendemail.chainreplyto' configuration
- value; if that is unspecified, default to --chain-reply-to.
-
--compose::
Use $GIT_EDITOR, core.editor, $VISUAL, or $EDITOR to edit an
introductory message for the patch series.
Only necessary if --compose is also set. If --compose
is not set, this will be prompted for.
---signed-off-by-cc::

CONFIGURATION
-------------
-sendemail.identity::
- The default configuration identity. When specified,
- 'sendemail.<identity>.<item>' will have higher precedence than
- 'sendemail.<item>'. This is useful to declare multiple SMTP
- identities and to hoist sensitive authentication information
- out of the repository and into the global configuration file.
sendemail.aliasesfile::
To avoid typing long email addresses, point this to one or more
Format of the file(s) specified in sendemail.aliasesfile. Must be
one of 'mutt', 'mailrc', 'pine', or 'gnus'.
-sendemail.to::
- Email address (or alias) to always send to.
-
-sendemail.cccmd::
- Command to execute to generate per patch file specific "Cc:"s.
-
-sendemail.bcc::

-
-sendemail.chainreplyto::
- Boolean value specifying the default to the '--chain_reply_to'
- parameter.
-
-sendemail.smtpserver::
- Default SMTP server to use.
-
-sendemail.smtpserverport::
- Default SMTP server port to use.
-
-sendemail.smtpuser::
- Default SMTP-AUTH username.
-
-sendemail.smtppass::
- Default SMTP-AUTH password.
-
-sendemail.smtpencryption::

- appropriate port), or 'tls' for TLS. Takes precedence over
- 'smtpssl' if both are specified.
-
-sendemail.smtpssl::
- Legacy boolean that sets 'smtpencryption=ssl' if enabled.

-is under consideration.
-
-Implementation note. For performance reasons, 'git-diff-tree'
-uses the pathname parameters on the command line to cull set of
-filepairs it feeds the diffcore mechanism itself, and does not
-use diffcore-pathspec, but the end result is the same.

diffcore-break: For Splitting Up "Complete Rewrites"
----------------------------------------------------
It takes one to three parameters. The first is the name of the file
that the commit log message. The second is the source of the commit
-message, and can be: `message` (if a `\-m` or `\-F` option was
-given); `template` (if a `\-t` option was given or the
+message, and can be: `message` (if a `-m` or `-F` option was

(if a `.git/SQUASH_MSG` file exists); or `commit`, followed by
-a commit SHA1 (if a `\-c`, `\-C` or `\--amend` option was given).

-three commits "old->a->b->c", and you notice that "a" was broken, but you
-want to save "b" and "c". What you can do is
-
- # Create a branch "broken" that is the current code
- # for reference
- git branch broken
-
- # Reset the main branch to three parents back: this
- # effectively undoes the three top commits
- git reset HEAD^^^
- git checkout -f
-
- # Check the result visually to make sure you know what's
- # going on
- gitk --all
-
- # Re-apply the two top ones from "broken"
- #
- # First "parent of broken" (aka b):
- git-diff-tree -p broken^ | git-apply --index
- git commit --reedit=broken^
-
- # Then "top of broken" (aka c):
- git-diff-tree -p broken | git-apply --index
- git commit --reedit=broken
-
-and you've now re-applied (and possibly edited the comments) the two
-commits b/c, and commit "a" is basically gone (it still exists in the
-"broken" branch, of course).
-
-Finally, check out the end result again:
-
- # Look at the new commit history
- gitk --all
-
-to see that everything looks sensible.
-
-And then, you can just remove the broken branch if you decide you really
-don't want it:
-
- # remove 'broken' branch
- git branch -d broken
-
- # Prune old objects if you're really really sure
- git prune
-
-And yeah, I'm sure there are other ways of doing this. And as usual, the
-above is totally untested, and I just wrote it down in this email, so if
-I've done something wrong, you'll have to figure it out on your own ;)

-To syntax highlight git's commit messages, you need to:
- 1. Copy syntax/gitcommit.vim to vim's syntax directory:
- $ mkdir -p $HOME/.vim/syntax
- $ cp syntax/gitcommit.vim $HOME/.vim/syntax
- 2. Auto-detect the editing of git commit files:
- $ cat >>$HOME/.vimrc <<'EOF'
- autocmd BufNewFile,BufRead COMMIT_EDITMSG set filetype=gitcommit
- EOF
+Syntax highlighting for git commit messages, config files, etc. is
+included with the vim distribution as of vim 7.2, and should work
+automatically.
+
+If you have an older version of vim, you can get the latest syntax
+files from the vim project:
+
+ http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/git.vim
+ http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitcommit.vim
+ http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitconfig.vim
+ http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitrebase.vim
+ http://vim.svn.sourceforge.net/viewvc/vim/trunk/runtime/syntax/gitsendemail.vim
+
+To install:
+
+ 1. Copy these files to vim's syntax directory $HOME/.vim/syntax
+ 2. To auto-detect the editing of various git-related filetypes:
+ $ cat >>$HOME/.vim/filetype.vim <<'EOF'
+ autocmd BufNewFile,BufRead *.git/COMMIT_EDITMSG setf gitcommit
+ autocmd BufNewFile,BufRead *.git/config,.gitconfig setf gitconfig
+ autocmd BufNewFile,BufRead git-rebase-todo setf gitrebase
